`
`Apodization refers to the Uniformity of illumination in the entrance pupil of the system. By default. the pupil is
`always illuminated uniformly. However, there are times when the pupil should have a nan-uniform illumination.
`For this purpose. ZEMAX supports pupil apodization. which is a variation of amplitude over the pupil.
`Three types of pupil apodization are supported: uniform, Gaussian. and tangential. For each type (except
`uniform). an apodization factor determines the rate of variation of amplitude in the pupil. See the discussion on
`apodization types and factors in the chapter "System Menu“.
`ZEMAX also supports user defined apodizations, which may be placed on any surface. Surface apodizations
`behave differently than pupil apodizations. because surfaces need not be located at a pupil. For more information
`on surface apodizations. see the "Surface Types" chapter under "The User Defined Surface" section.
`
`Back focal length
`
`ZEMAX defines the back focal length as the distance along the Z axis from the last surface made of glass to the
`paraxial image plane. it no surfaces are made of glass. the back focal length is the distance from surface 1 to the
`paraxial image plane.
`
`Cardinal planes
`
`The term cardinal planes (sometimes called cardinal points) refers to those special coniugate positions where the
`object and image surfaces have a specific magnification. The cardinal planes include the principal planes, where
`the magnification is +1 . the nodal planes. where the angular magnification is +1. the anti-nodal planes. where the
`angular magnification is -1. and the focal planes, where the magnification is 0 for the image space focal plane
`and infinite for the object space focal plane.
`Except for the focal planes. the cardinal planes are conjugates with each other. that is. the image space principal
`plane is conjugate with the object space principal plans. etc. if the lens has the same index in both object space
`and image space, the nodal planes are identical to the principal planes.
`ZEMAX lists the distance from the image surface to the various image space planes. and lists the distance from
`the first surface to the various object space planes.

`
`Diffraction limited
`
`
`
`
`
`The term diffraction limited implies that the performance of an optical system is limited by the physical .
`I
`diffraction rather than imperfections in either the design or fabrication. A common means of detain-ht.
`
`system is diffraction limited is to compute or measure the optical path difference. If the peak to valley 0 _
`than one quarter wave. then the system is said to be diffraction limited.
`
`There are many other ways of determining if a system is diffraction limited. such as SItrehI ratio. HI I
`
`standard deviation. maximum slope error, and others. It is possible for a system to be considered diffracti
`by one method and not diffraction limited by another method.
`
`On some ZEMAX plots. such as the MTF or Diffraction Encircied Energy. the diffraction limited respo
`optionally shown. This data is usually computed by tracing rays from a reference point in the field of via
`
`apodization. vignetting, F/it's. surface apertures. and transmission may be accounted for, but the optics
`difference is set to zero regardless of the actual (aberrated) optical path.
`.
`
`For systems which include a field point at 0.0 in both it and y field specifications (such as 0.0 x angle elicit]
`angle), the reference field position is this axial field point. If no (0. 0) field point is defined. then the field coord
`of field position 1 are used as the reference coordinates instead.
`
`
`
`Edge thickness

`"
`
`_
`
`.
`
`ZEMAX uses two different definitions for the term "edge thickness". Usually. the edge thickness is oori‘iptit'etttil're“t

`

`is the axial thickness of the surface. Note that the -'

`When drawing all configurations, an offset may be added to each configuration in the x. y. and 2 directions
`indgpendgnuy' The offsets may all be zero if desired. It the offsets are zero. then all the configuratiOns are
`Bupafimpoged- otherwise. the configurations are all displaced frOm one another by the specified amount. Note
`that all offsets are defined from the global coordinate reference surface pesttron. The global coordinate reference
`surface is defined on the Miscellaneous tab of the System. General dialog box. If all offsets are zero. the multiple
`Configurations are all overlapped at the global coordinate reference surface.
